Don't let these brain teasers frost you!

 Solve the puzzles in the back of your Inking About Thinking journal. Always add the date and title of the problem. 

  

 Evaluate each problem that you complete. How did it make you think? 

3- A snap!  5- Got it once I thought about it  8- AHA! I persevered and finally got it. 10 - Tah Dah! I can't believe I solved it!)

 

 

         

SOCK IT TO 'EM MATH PROBLEMS

     ....in honour of Albert Einstein who never wore socks.

 

 

Read the article " Why Einstein Stopped Wearing Socks".

Record the answer and 5 other interesting facts you did not know about this quirky famous physicist. 

 

1. MIXED UP SOCKS

 

Start with three pairs of socks. Now mix them up so that no mismatched pair is the same as another mismatched pair.

Socks

Now try it with four pairs of socks. Is there more than one way to do it?

 

 

 

2.THE SOCK DRAWER PROBLEM

 

 

 

You are about to leave for holiday, but you forgot your socks! You race back to your room, but all the lights are off , so you can't see the colour of the socks. Never mind, because you remember that in your drawer are ten pairs of white socks, ten pairs of black socks, and eleven pairs of blue socks. You can only take one sock from the drawer at a time. How many of your socks do you need to take before you can be sure you have at best on matching pair?

5.  DOUBLET WORD PUZZLES

 

    Lewis Carroll 1832- 1898 

 

The word game "Doublet" was invented by Lewis Carroll, the author of the children's classic, "Alice in Wonderland". Carroll was also a mathematician known to his fellow teachers as Charles L. Dodgson. The rules of the puzzle are simple. Transform one word int another by changing a single letter in each step, so that each link in the chain is a valid word. For example, to change MORE into LESS with 3 links:

MORE - lore - lose - los- LESS   Links do not include the two given words. There may be more than one solution.

 

Try these doublet challenges! Use your mathematical reasoning abilities!

 

4 LINKS 

HARD  - EASY

HEAD  - TAIL

 

5 LINKS

SLEEP -  DREAM

 

6 LINKS

BLACK - WHITE

 

 

6. Paralyzing Number 'Numbers' ( numb - deprived of feeling through cold or shock)

 

Magic Squares

Magic Squares date back over 4,000 years to ancient China and have existed throughout history and in many different parts of the world. The magic lies in the fact that when the numbers in each row, column, and main diagonals of the square are added together, the sum is always the same. These number puzzles have fascinated some of the world's most brilliant thinkers, including the eighteenth century American Benjamin Franklin. He studied and composed some amazing magical squares, even going so far as to declare one square “the most magically magical of any magic square made by any magician."

.

Benjamin Franklin (1706-1790), American scientist, inventor, statesman, philosopher, economist, musician, and printer, invented the 8x8 magic square in his spare time.

It is a pure magic square in that it utilizes the consecutive counting numbers from 1 to 64. View his 8 x8 Magic Square

 

Use your math skills to complete the magic squares below. Remember that the values in each of the rows, columns and diagonals must add up to the same sum, known as the "magic number'.
